Across the United States, widespread demonstrations are planned in opposition to President Trump, notably including a pivotal "No Kings" march in Philadelphia, while the President attends a military parade in Washington commemorating the Army's 250th anniversary; these protests have been further inflamed by federal immigration law enforcement investigations and the deployment of National Guard troops and Marines to Los Angeles in response to increasingly volatile demonstrations, prompting responses from authorities and law enforcement involving curfews, tear gas, rubber bullets, and flash-bang grenades; multiple states have mobilized National Guard personnel to support maintaining order, signaling a zero-tolerance policy towards violence and unlawful conduct; these protests, orchestrated by the 50501 Movement, aim to counteract perceived authoritarian actions by the Trump administration, with expectations of the largest single-day mobilization since Trump's return to office, encompassing events at approximately 2,000 locations nationwide.
